Good. One thing I do not like about it. It follows the tab. So if you reply to a post and it opens in the same tab it will reload at the interval you set. If you have written some of the post but not finished and it kicks in you lose what you have written. Solution is to open the editor in a new tab.
Google Chrome handles it better with the auto-reload add on. It follows the webpage, so you do not run into that frustrating wipe out.
